The amount of available wifi space is slowly shrinking, according to Pittsburgh’s WTAE news outlet. In both a video segment and article on the WTAE website, experts point out that wifi hotspots were built for laptops that stay in place. But as more locations create wifi hotspots, it may cause interference with other hotspots and cause a decrease in capacity. This strain could even impact healthcare facilities since more and more doctors now use tablets in hospital environments where lives are at risk when you cannot communicate the telemetry you need between a room and the system between different devices, hospitals and so forth.
